🔧 Technical Overview – What Is an HRC Rubber Coupling?

The HRC (Highly Resilient Coupling) is a flexible jaw-type coupling consisting of:

1. Two Metal Hubs

• High-strength cast iron / steel
• Claw-type tooth design
• Precision machined for balanced rotation
• Can be bored to specific shaft diameters

2. A Star-Shaped Elastomer (Rubber Spider)

• Oil-resistant reinforced rubber
• Designed for compression-based torque transfer
• Electrically conductive
• Heat and abrasion resistant
• Available in standard and high-torque grades

3. Optional Taper Bush or Pilot Bore

• H (Bush Type)
• F (Flange Type)

This configuration ensures smooth, quiet, and durable power transmission even in harsh industrial environments in places such as Sandakan palm oil mills, Miri offshore plants, Kuching factories, and Brunei power stations.

 

⭐ Ultra-Detailed Key Features of HRC Rubber Couplings

1. High Torque Transmission with Elastic Buffering

The star-shaped rubber spider transmits torque in compression mode, allowing higher load absorption and preventing metal-to-metal contact.

2. Superior Vibration Damping

Reduces:

• Torsional vibration
• Sudden torque shocks
• Load fluctuations
  Ideal for motors running at inconsistent speeds (common in palm oil mills and compressors).

3. Misalignment Handling Capability

Compensates for:

• Parallel misalignment (0.5–1.2 mm)
• Angular misalignment (up to 1°)
• Axial float (up to 1–2 mm)

Perfect for equipment in uneven floors/old plants in Labuan, Kuching, Bintulu, Tawau.

4. Fail-Safe Performance

Even if the rubber spider wears out, the claw hubs maintain limited drive to prevent sudden machine shutdown.

5. High Durability & Puncture-Proof Elastomer

Engineered to withstand:

• Mineral oils
• Grease
• Heat
• Dust
• Chemical vapours
• Moisture in coastal towns like Kota Kinabalu, Semporna, Muara, Kudat

6. Quick & Easy Installation

Split hub options reduce downtime for industries in remote towns such as Telupid, Pitas, Kapit, Song.

7. Maintenance-Free Operation

No lubrication required — long operating life even under continuous-duty cycles.

🔩 Installation Guide for HRC Rubber Couplings (Step-by-Step)

Step 1: Shaft Preparation

• Clean both shafts
• Ensure no burrs or rust
• Measure shaft diameters accurately

Step 2: Fit Bushes or Hubs

• Insert taper bush (if using H-type)
• Align keyway with shaft key

Step 3: Position Hubs

• Slide each hub onto opposite shafts
• Maintain correct shaft spacing (S-distance)

Step 4: Insert Rubber Spider

• Fit elastomer star evenly
• Ensure the teeth engage fully

Step 5: Align Shafts

• Use straightedge or laser alignment
• Correct any parallel or angular deviation

Step 6: Tighten Bolts

• Tighten taper bush bolts gradually and evenly

Step 7: Run Test

• Rotate by hand
• Start machine slowly
• Check for abnormal vibration
